1. Download latest gumstix-buildroot;
2. Download the latest buildroot (the original buildroot itself), from svn;
3. Copy the /toolchain/gcc/gcc-4.2.1 directory from buildroot to gumstix-bu=
ildroot
4. Modify the file /toolchain/gcc/Config.in, (just copy and paste some bloc=

5. Build.

I'll test the httpd/sshd stuff on gumstix later after work to see if it is =

Does anyone know how to change the config file to get bluetooth working

now things are getting weird...now I cannot connect at all.
I tried several more times with the loadb command and it didn't worked. I
also tried a different serial cable. I rebooted everything and now I don't
even get the GUM> prompt or any communication at all. Did somehow things get
bricked? I didn't touch uboot at all. I did do "pro on 1:0-1 && jera all" to
see if it would take the loadb then, but it didn't change anything and I was
able to reboot back to the GUM> prompt several times after issuing that
command.

I had the same problem with a connex, a netCF (connex version) and a second
recently purchased robostix (the network did not start with the new robostix
attached, but was fine with the original robostix). Unfortunately, in
attempting to figure out what was going on, the connex board has died.
I did exactly what you have: connected the power to the netCF, whilst the
robostix was connected, I think that this has done some permanent damage to
the connex board as it no longer works, even on it own.

Hi,
I followed the instructions from Jason and configured Linux to have the FB
attached to tty0. The diffs of my additions to Linux .config were:

< CONFIG_FONT_8x16=y
---
> # CONFIG_FB_VIRTUAL is not set
and I added the CONFIG_INPUT=y and CONFIG_VT=y to my initrd Linux as
well to provide kernel support for stuff fbcon.ko needs.
I modprobe fbcon via /etc/modules, without attaching a getty on tty0 since
I only need tty0 to display ASCII chars.
When I do a "echo abcdef >/dev/tty0" I do see something displaying on
the LCD, but the font is pretty messed up (bunch of faint dots). I'm
supposedly using the 8x8 or 8x16 default fonts, but have no idea what
is really happening.
Also, pxafb seems to shut off after some time, probably on request from
fbcon.
I know the pxafb is set up right because the penguin.ppm displays
properly using ppmv.
Could somebody give me some hints on what to do at this point?
Thanks.

Hey
One more thing... you may do well to avoid servos. A model that uses a
servo to change the blade pitch for example. It's simpler if
everything is driven by a simple variable voltage. They have 3-channel
models basically using three motors running at variable speeds to do
everything.

At least a few pages are in english; especially the (most
important) description of the flight-control. An english
discussion board exists as well.
I think the biggest challenge will be to order all the
necessary parts from germany...

The robostix is a 5v device. When you use the 4v wallwart, it winds up
seeing only about 3.5v and adding the NetCFvx probably draws more than
the robostix voltage regulator can deliver at that low voltage.
I've only ever used a 5v adapter and haven't had any issues with the
robostix/verdex/netCF-vx stack.

So, when you power the robostix, the gumstix boots, but the netCF-vx =
doesn't?
Seems like a weird problem. I know I've had a robostix/verdex/netCF-vx
stack working in the past, so at least it's possible.
It sounds like a contact problem (in the 60-pin hirose connector)
between the robostix and the verdex.

If you power the expansion boards, then the robostix will never be
powered and you won't be able to use it. If you power the robostix,
then it will provide power for the expansion boards.

I'm trying to reflash my gumstix with a new jffs2 image and it fails when
copying over the file using kermit. I can connect to the gumstix via the
serial fine and am using the following kermit settings from the wiki:
set carrier-watch off
set speed 115200
set file type bin
set reliable
fast
set flow-control none
set rec pack 4096
set send pack 4096
set window 5
set prefixing all
after I type in loadb a200000000 and uboot says it is waiting for the file,
I switch to Kermit and trying sending and it dies after retrying 12 times to
send a packet. Oddly, I did this only a week ago and it worked fine. Then I
updated uboot to the latest as well without any problems.
Any ideas?
Also, is it possible to only update the kernel and not the whole file
system? What would the flash commands be to unlock just the kernel area and
to protect the FS?
Thanks, Mark

Hi,
Yes it has the console line.
Even if I wait an hour it will not show anything.
It is btw due to my own fault, before it did boot but the dhcp did not =
work, after some attempts due to underknowledgement on my side I seem to =
have broke something (hardware wise?)
But since I just got the console-vx today and was suprised it does show =
uboot and things actually seem ok.
So figured I could get it working but it does not tell me what is wrong.
My guess is that out of some frustration I was not carefull enough last =
time and damaged the ram orso, just would be nice to know for sure..
The mtest shows no error it seems..
And I can load a kernel over nfs.
Any clues/ideas are more then welcome, never really got to use this =
verdex...
Thanks,
Jean-Paul

gpio-event only knows about GPIOs conencted directly to the processor.
Currently, you'd need to poll the gpios on the robostix in order to
see if they've changed.

So, when you power the robostix, the gumstix boots, but the netCF-vx doesn't?
Seems like a weird problem. I know I've had a robostix/verdex/netCF-vx
stack working in the past, so at least it's possible.
It sounds like a contact problem (in the 60-pin hirose connector)
between the robostix and the verdex.

If you power the expansion boards, then the robostix will never be
powered and you won't be able to use it. If you power the robostix,
then it will provide power for the expansion boards.

iirc this thing: <http://hybrid.stanford.edu/index.php?section=37&gt;
has gumstix on board. It might be robostix too.

Do you have the "console=ttyS0,115200n8" in your u-boot's bootargs?
If not, then it's probably running just fine, you're just not seeing
any output because it's not being sent to the serial port. If you
wait a while, and still have the getty on ttyS0 in /etc/inittab, then
eventually you'll get a login prompt.

The current state of bluetooth in the buildroot is that it's building
the latest bluez versions of things, but the config files and startup
scripts have changed pretty substantially in the latest revs of
bluez, and I haven't had time to go through and set up the configs to
more-or-less match the way that the old config was set up -- ie to
start up hcid, rfcommd and pand on boot. If you're capable of
setting up the config files the way you want them to be yourself,
then you can go ahead and use the latest rev.
